CVE-2026-91865: Vulnerability in Apache Software Foundation Apache Neethi
A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
AI Analysis
Technical Summary
CVE-2026-91865 describes a denial of service vulnerability in Apache Neethi caused by repeated policy references in WS-Policy documents. The repeated references cause the normalization process to re-expand the same references exponentially, consuming large amounts of CPU and memory resources. This can degrade service availability. The Apache Software Foundation has addressed this vulnerability in version 3.2.4.
Potential Impact
Exploitation of this vulnerability can lead to denial of service by exhausting CPU and memory resources on systems processing crafted WS-Policy documents with repeated references. This impacts service availability but does not indicate code execution or data compromise.
Mitigation Recommendations
Users are advised to upgrade Apache Neethi to version 3.2.4 or later, where this vulnerability is fixed. No other mitigations are indicated.
